This page is an advanced version of Pronunciation and decoding exercises: /s/ vs /z/. It can also be used for self study.

Many words that are spelled with "s" are pronounced with /s/ while others are pronounced with /z/. Students who have never heard the words must memorize them. Heteronyms are particularly relevant here.

This article doesn't explain other sounds, such as /ʃ/ or /ʒ/.

Initial

When looking at a written word there is never a doubt whether it is pronounced /s/ or /z/ at the beginning of the word. Besides, there are only two words with other alternatives: sugar and sure.

Spelling /s/ /z/
c ceiling - cent - center - certain - ceremony - cigarette - cinema - circle- city - civilian - cycle
s sad - sale - same - say - scar - school - sea - seat - second - see - sell - send - sense - service - set - several - side - sign - since - sing - sink - sit - ski - sky - sleep - small - smile - sneeze - soap - social - some - song - soon - sort - sound - speak - spend - squeeze - staff - stand - start - stay - stop - strong - study - suggest - suit - sun - swim - swing - symbol - system
